Description

This driving simulator study investigated a drivers' ability to resume manual control of their level-3 automated vehicle in response to system failure. Participants were asked to engage in non-driving task which required them to input text on a screen. A take-over request (TOR) was then provided under conditions where the TOR was and was not displayed on the task screen, and the effects with respect to system operation during the TOR were investigated. Regarding lateral operation, amount of lane departure was larger under conditions of suppressing control force rather than under conditions of continuing control force. Contrastingly, risk of collision was lower due to the driver’s suppression of longitudinal operation when the TOR was provided.
